In shallow coastal ecosystems dominated by seagrasses, nutrients limit primary production under low nutrient (oligotrophic) condition while light becomes the limiting factor under high nutrient (eutrophic) condition. In the conceptual model given below, identify which group of primary producers (i.e. seagrasses, macroalgae, phytoplankton) corresponds to each of the line graphs by filling in the blank boxes. Explain your answer.

Physical and Chemical features

The physical property of a compound could be determined without modifying the originality of the compound. Examples of physical properties are density, hardness, color, boiling, and melting point. The chemical property expresses the ability of a compound to undergo a particular chemical change.
